Answer:
Step-by-step explanation:
Let the angles be 4x , 5x
4x + 5x = 180   { supplementary}
       9x = 180
         x = 180/9
         x = 20
Larger angle= 5x = 5* 20 = 100
 
        
             
        
        
        
25-4x=16-4x
25-4x+4x=16-4x+4x
25=16

Answer:
Yes, the total cost of Lacey lesson is a split function of hours scheduled
Step-by-step explanation:
The amount Lacey pays for each hour of golf = $15
The amount Lacey pays for equipment rental = $10
The amount Lacy pays for equipment rental for a 3 hours long lesson = $5
Therefore, we have
Let C represent the total cost of Lacey lesson and let t represent the number of hours, we have;
C = $10 + t × $15 for 0 ≤ t ≤ 3
C = $5 + t × $15 for t > 3
Therefore, the total cost of Lacey lesson is a split function of hours scheduled
